Apparatus and method for generating link for each lane

Abstract

Disclosed are an apparatus and method for generating a link for each lane when there is a plurality of exit lanes. The apparatus may acquire information about a speed of a probe vehicle from the probe vehicle, and determine a section for generating a divided link along a lane, based on a speed difference of the probe vehicle in an exit direction.
